How to delete individual backup versions within an archive in ATI2018
After reconfiguring my NAS, my backup settings were reset and the backup schedule was set to 'Daily'. While away, the backup had time to run a few times, before I noticed, resulting in my NAS now being full (of backup files).
How do I remove the 2-3 last Backup versions in the current chain?
My settings:
- I am using the 'Differential' backup scheme
- 10 backup versions in each chain before a new full backup
- Maximum archive size is 15 TB
- Keep the initial full backup
I couldn't find a way of deleting backup versions in the GUI of ATI2018, so I thought of simply deleting the .tib files through Windows Explorer.
Before deleting, just to be sure, I searched the Acronis documentation pages, and eventually, I found this article, How to Delete Backups, relating to Acronis Backup 11.5, suggesting deleting individual backup versions from the CLI using the command acrocmd. Furthermore, they are saying not to "not delete backups manually from the file system (e.g. using Windows Explorer)". Since that would "leave the metadata outdated causing possible backup/cleanup failures."
I couldn't find any information of an equivalent to acrocmd in ATI2018, or how to do this via the command line. In fact, I actually found information about there existing no CLI at all for ATI, and information about it being removed in ATI2014.
I continued my search and found the article, Deleting backups in Windows Explorer fails with "Folder access denied", an article which actually refers to ATI. Here they say, "we recommend deleting backups in product interface." But they don't specify how and where in the GUI you can do this. I then went back and thoroughly explored the GUI and I can't find any way of deleting individual backups.

I am a big fan of Acronis products, and I do recommend them, but this whole ordeal has been quite frustrating - not being able to find any information. It is actually shocking to me that such a simple thing isn't described anywhere within the documentation of such a premium and costly product such as ATI. I recently upgraded all our 5 licenses from ATI2017 to ATI2018, as well, meaning that I am stuck with ATI2018 for a while now.
